I was looking at The Attitude seed bank (a site sponsor) for the various seeds they have to offer. They have seeds by KC Brains that are around $20 U.S. funds for 10 seeds. Attitude also gives away free seeds with your order. The more you order, the more freebies you get. The weekend of March 5th they are having a special freebie offer. Also, while going through the order process there is a spot for a discount code. If you type in 420, you will get an aditional 10% off your order.
Give them a try.
